While you will, from time to time, come across Chemicals outside of their Storerooms, these aren't listed, as all available Chemicals are present and accounted for in multiple Storerooms, and there are more than enough available to research everything in the game without having to scrounge through evey desk and crate you find. Literally in the beginning of the game after intense and atmospheric intro, escaping the decompression and watching someone being chased by a zombie, there is this door. Each deck houses a Chemical Storeroom where its selection of Chemicals are held. I remember the first time I played this game, because it didnt lasted for very long. In System Shock 2, every energy-using item instead has its own separate internal battery supply, and the only connection to System Shock 1 is that theres recharge stations and those freely restore everything in your inventory in an approximation of System Shock 1 having recharge stations fully restore your global energy meter.

If you've invested in Research to give yourself an edge over the Many, then you'll want to take a look at the list below for locations of all the Chemicals in System Shock 2.
